表面处理对NR粘合性能的影响

研究机械打磨、硫酸处理和次氯酸钠处理3种表面处理方法对NR粘合性能的影响。结果表明：经过硫酸适当处理后，NR硫化胶与水的表面接触角明显减小，表面润湿性改善，粘合性能显著提高；硫酸处理NR硫化胶的粘合性能优于机械打磨和次氯酸钠处理的NR硫化胶。;The influence of three surface treatment methods on the interface adhesion property of NR was investigated,i.e.mechanical polishing，sulfuric acid treatment and sodium hypochlorite treatment.The results showed that，treated with sulfuric acid，the contact angle of NR vulcanizate with water decreased significantly，the wettability improved，and the adhesion property increased significantly.The adhesion property of NR vulcanizate treated with sulfuric acid was better than that of NR vulcanizate treated with mechanical polishing or sodium hypochlorite
